Original application filed October 24, 1902, Serial No. 128,521. Divided and this application fileclMay 4, 1903. Serial No.155,459. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM J. LUTTON, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Pattern-Chains for Looms, of which the following is a specification.

This invention relates to an improvement in looms, and has more particularly for its object to provide a new pattern-chain whereby the heddles may be operated to produce a great variety of weaves with a pattern-chainof very few bars, thus materially reducing the cost of the pattern-chain and also the weight thereof.

A still further object is to provide a new pattern-chain in which rocking bars are provided with mutilated spools, so that when the bars are turned in one direction the spools may be used to operate the heddles and when turned in the other direction will fail to operate the heddles.

A practical embodiment of my invention is represented in the accompanying drawings, in which 7.

Figure 1 is a transverse section through a loom embodying my invention. Fig. 2 is an enlarged detail side view of a portion of the loom, certain of the parts being broken away to more clearly show the operation of my new pattern-chain. Fig. 3 is a detail sectional view showing the means for adjusting the indicator-bar. Fig. at is a detail view showing the means which I employ-for preventing the turning of the indicator-bar as it is reciprocated in theloom-frame. Fig. 5 is a detail view of the driving pattern-chain shaft with its attached sprocket-wheels and guidingwheel. Fig. 5 is a similar view of the lower idler-shaft, its sprocket-wheels, and guidingwheel. Fig. 6 isa transverse vertical section through the pattern-chain and its support, showing the mutilated spools in different positions and also showing several full spools. Fig. 7 is a top plan of a portion of the pat ternchain and its support, showing the spools in different positions. Fig. 8 is a transverse section through one of (hepattern-chain bars, showing the single-spur tripper, which is controlled by the indicatorroller. Fig. 9 is a transverse section through the bar, showing the double-spur tripper operated by the permanent controlling-roller. Fig.'10 is a transverse section through the bar, showing one of the mutilated spools in its bottom position. Fig. 11 is a similar view showing one of the mutilated spools in its top position. Fig. 12 is a similar view showing one of the full spools. Fig. 13 is a detail view, in top plan, of the support at one side of the pattern-chain; and Fig. 14 is a similar view of the support at the other side of the pattern-chain.

The loom-frame herein represented is denoted by 1. Two heddles 2 and 3, with their operating mechanisms, are also represented.

The pattern-chain is composed of a series of angular bars 4, connected at their opposite ends by two series of links 5 and 6. Inthe present instance I have shown these bars 4 as being square in cross-section. The space between the two series of side links 5 and 6 upon each of the bars 4 is filled by a plurality of collars '7 of equal lengths. Some of these collars 7 are provided with full spools 8, which will always raise one of the hedrllecontrolling bars when brought in contact therewith. Others of the collars 7 are provided with mutilated spools 9. The collars 7 which have the mutilated. spools 9 thereon are keyed to turn with the bar 4:, preferably by providing the said sleeves with angular sockets corresponding to the shape in crosssection of the said bar. lar bar-such, for instance, as the upper bar shown in Fig. ,6, which is the same bar as the lower bar shown in Fig. 7-two of the mutilated spools are placed upon the bar opposite to two others of the mutilated spools. This bar is also provided with a complete spool 8. It will thus be seen that when this bar is turned to one position one set of two of the mutilated spools 9 will be caused to engage the heddle-controllin g bars and when the said bar is turnedv into another. position, a halfrevolution from the first-named position, the other two mutilated spools 9 will be brought into position to raise their corresponding heddle-controllingbars. Therefore whenever this particular bar is brought into position to operate the heddles the full spools will always operate the heddle-controlling bar and two of On any one particuthe mutilated spools 9 will operate their corresponding heddle-controlling bars. Each of the cross-bars 4 of the chain is provided near one end with a single-spur tripper fitted to be engaged by the indicator-controlled roller when in its lower position. This single-spur tripper is constructed by providing a collar 10 of the same length as the collars 7 and providing the said collar 10 with a spur 11. This tripper is fixed to rock with the bar 4, preferably by providing the socket therethrough to correspond with the shape in cross-section of the said bar. Each of the bars 4 is provided at one end, preferably the end adjacent to the series of side links 6, witha double-spur tripper fixed to rock with the said bar. This double-spur tripper is made, preferably, by providing a collar 12, having a socket therethrough corresponding to the shape in crosssection of the bar 4, which collar is provided with oppositely-extended spurs 13 and 14, arranged at right angles to the single spur 11 of the single-spur tripper. These double-spur trippers are fitted to be engaged by a controlling-roller carried by the frame, which will be hereinafter described.

The pattern-chain passes around an upper driving-shaft 15 and a lower idler-shaft 16, in engagement with the usual pairs of sprocketwbeels 17 and 18, which engage the series of side links 5 and 6. The series of side links 5v and 6 of the pattern-chain rest upon rigid guides 19 and 20, secured to the frame as they pass from the sprocketwheels 17 to the sprocket-wheels 18. The said series of side links 5 and 6 are also supported for a part of the distance as they pass from the sprocketwheels 18 to the sprocket-wheels 17 by guides 21 22, which are held in position by pairs of looped supporting-bars 23 24, which connect the guides 21 22 with the supports 19 and 20. The recesses through the side links are sufficiently large to permit the angular cross-bars 4 to freely rock therein. The bars 4 are prevented from turning while passing around the driving-shaft 15 by means of a guiding-wheel 25, which is in alinement with the double-spur trippers 13 and 14. The mutilated spools 9 upon each bar as it passes beneath the beddle-controlling bar will therefore be held in its proper positions to raise the bars to pass idly beneath the same. The bars 4 are also held from turning while passing around the idler-shaft 16 by means of a similar guidingwheel 26, also in alinement with the doublespur trippers 13 and 14. The means which I employ for rocking the bars a half-revolution in one direction by two successive movements and a half-revolution back by two successive revolutions when so desired is constructed and arranged as follows: A box-chain 27 is provided at suitable intervals with spools 28, which box-chain passes around a sprocket- Wheel 29 on the upper driving-shaft 15 of the pattern-chain.

A rock-bar 30, similar to the heddle-controlled bars, is mounted in position to be enchain, the said rock-bar 30 being fitted to raise and lower an indicator-roller 31 out of and into the path of the single-spur trippers 11. This rock-bar 30 is connected to the roller 31 as follows: The roller 31 is carried by the lower end ofa vertically-reciprocating rod 32, the upper end of which is adjustably secured to one arm 33 of a rocking lever pivoted to the frame at 34, the other arm 35 of the said lever being connected to the free end of the rock-bar 30 through a link 36. The Vertically-reciprocating rod 32 passes through a horizontal rail 37 of the frame and is prevented from turning therein preferably by squaring the rod 32 where it passes through the rail 37, as shown at 38.

The double-spur-tripper controlling-roller gaged and raised by the spools 28.01 the box- 39 is mounted in the free end of an arm 40,

supported by the rail 37, so that the said roller 39 is located in the path of the double-spur trippers. Two fingers 41 42 are secured to the guide 21, the finger 41 being extended into the path of the single-spur tripper 11 and the finger 42 being extended into the path of the double-spur tripper 13 14. An intermediate guide-finger 43 is arranged to hold the chain down against its support 19 while the bar is being turned by the preceding singlespur tripper because of its engagement with the finger 41. e

The pattern-chain is placed in position around the shafts 15 and 16, with the singlespur trippers projecting outwardly from the chain. \Vhen the bars of the chain are in this position with the single-spur trippers projecting outwardly, the double-spur trippers will be located longitudinally of the chain and a certain series of mutilated spools willbe in position to raise their corresponding heddle-controlling bars, while the other series of mutilated spools will be in position to pass freely under their corresponding heddle-controlling bars without operating the same. As the bars of the chain leave the sprocketwheels 18 on the shaft 16 the single-spur trippers 11 projectoutwardly. If it is desired to turn a bar a half-revolution to turn certain of its mutilated spools out of position to engage their heddle-controlling bars and the other mutilated spools into position to engage their heddle-controlling bars, it is done as follows: One of the spools 28 upon the boxchain 27is brought into engagement with the rock-bar 30 in time to lower the single-spurtripper controlling-roller 31 into the path of the single-spur tripper carried by the bar which it is intended to turn. As the patternchain is moved along by the driving-shaft l5 and its sprocket-wheels 17 the roller will turn the bar 4 a quarter-revolution, thus bringing the double-spur tripper 13 14 into a position at right angles to the chain. As the chain continues to move forwardly the controllingroller 39 will engage the spur of the doublespur tripper which projects outwardly and turn the bar 4 another quarter-revolution.

This will bring the mutilated spools which were projecting outwardlyinto a position projecting inwardly and also bring the mutilated spools which were projecting inwardly into a position projecting outwardly from the chain. The bar passes around the driving-shaft 15 beneath the heddle-controlling bars in this position. When the box-chain 27 fails to lower the controlling-roller 31 into the path of the single-spur trippers 11, the bars will travel along up to the heddle-controlling bars without being shifted, for the reason that the controlling-roller 39 will pass along the outer sides of the double-spur trippers 13 14 without turning the same, as the said double-spur trippers will be arranged longitudinally ,of the chain. The bars are always returned to their normal position before they reach the shaft 16 by the following mechanism: As the pattern-chain leaves the shaft 15 the finger 41 will engage any inwardly-projected singlespur trippers 11, and thus turn the bar 4 backwardly a quarter-revolution. While this is being done the pressure of the guide-finger 43 holds the chain firmly down upon its support 19. Before the chain reaches the shaft 16 the finger 42 will engage any inwardlyprojecting spur of the double-spur trippers 13 14, thus turning the bars 4 a quarter-revolution back to their normal position.

By the arrangement hereinabove described it will be seen that I am enabled to produce a great many changes in the weave with a very short chain, for the reason that the changes in the pattern can be controlled from the box-chain, so as to produce a great number of combinations in the mutilated spools.

In the device herein shown the loom will be weaving the ground-weave when the single-spur trippers are projecting outwardly, and the cross-stripe weave may be called in at any time from the box-chain by lowering the roller 31 into position to engage one of the outwardly-projected single-spur trippers for bringing the double-spur tripper into position to be engaged by the roller 39 for completing a half-revolution of the pattern-chain bar, as has been heretofore clearly described.

The present application is a division of the copending application filed by me on the 24th day of October, 1902, upon which Patent No. 729,880, dated June 2, 1903, was granted, and the parts which I have shown and described herein, but have not claimed, form the subject-matter of the patent above referred to.
